Emerson Process Management has introduced the Fisher FIELDVUE DVC6200p series of digital valve controllers. The DVC6200p series is an ideal solution for applications in which accessibility, extreme temperatures up to 120°C, extreme vibration or confined space make integral mounting difficult or impractical.
Industries such as pulp and paper, and metal and mining have typically preferred to isolate valve-mounted instruments from harsh environments. With the remote mount version of DVC6200p, only the valve position feedback is mounted on the control valve, while the remainder of the digital valve controller can be mounted over 90m away in a less severe or more accessible environment. The remote valve mounted feedback unit utilises the patented FIELDVUE linkage-less, non-contact feedback technology, in which physical contact has been eliminated between the valve stem and the instrument. With no linkage to wear, loosen, corrode or vibrate, the feedback unit can withstand a plant’s operating extremes. Utilising the best of PROFIBUS PA, the DVC6200p series provides a wealth of alerts, trends and diagnostics to allow for visibility and control.
The DVC6200p supports enhanced device description (EDD) files that allow for quick and easy configuration. For more extensive parameterisation, leading PROFIBUS configuration tools can be used.
